6. When rolling silver sheet, it may be necessary to anneal the sheet after rolling it from to in thickness. For 14Kt gold, the annealing may be necessary after rolling from to Please note that the following is only a guide. Reduce wire by rolling two or three times in each groove, rotating the wire 90 degrees on each pass.
A three roll mill utilizes high shear force to disperse agglomerates, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other. The product is pulled through the gaps between the rollers.
